The Cosel MMC75A-1 is a triple-output open frame AC/DC converter designed for ITE (commercial) applications. It delivers +5V at 1.2A, +12V at 0.1A, and -12V at 0.1A from a wide input range of 85-132VAC (single phase) or 110-170VDC.
Key electrical specifications include a typical efficiency of 68% (at 100VAC full load), line regulation of 20mV (max) on the +5V output and 48mV on the ±12V outputs. Load regulation is 60mV (max) on +5V and 120mV on ±12V. Ripple and noise are 80mVp-p (max) on +5V and 120mVp-p on ±12V. The converter also includes overcurrent protection that activates above 105% of rated output and recovers automatically.
The unit is chassis-mountable and comes in an open frame package measuring 193.0mm x 93.0mm x 42.0mm. It operates over 0°C to +65°C with derating, and 20-90%RH (non-condensing). Storage temperature range is -20°C to +75°C. The MMC75A-1 complies with UL60950-1, C-UL, and meets DEN-AN requirements; conducted noise meets FCC-B.
